Following are the steps you must follow - 1. First you have to find the opening tail or neck of the balloon. 2. Push the opening of the balloon onto the nozzle of the pump until it looks airtight. 3. Hold the balloon in place while you press the nozzle to pump the helium into balloon until the desired inflation level is achieved. 4. Foil balloons are inflated through self-sealing valves located in the balloon necks. When balloons are fully inflated, remove the helium inflation nozzle and the balloons will seal automatically. 5. Tie a ribbon just below the value and use a balloon weight to keep it from flying away.
